ABSTRACT:
A carburetor for an internal combustion engine has a conduit through which air is drawn into the engine, a source of fuel, and means for delivering fuel from the source to the conduit for mixing with air to form an air-fuel mixture combusted in the engine. An improvement comprises a throttle valve positioned at the inlet to the conduit and movable between a closed and an open position to control the quantity of air drawn into the engine.
An outlet is defined for the fuel to be delivered to the conduit, fuel discharged through the outlet being atomized by the air flowing past the outlet.
The air flowing past the fuel outlet flows therepast at substantially sonic velocities thereby to improve fuel atomization and enhance mixing of the air and fuel.
